$PECIPICATION forming part of Letters Patent No. 452,997, dated May 26,1891.

Application filed February 7, 1891. Serial No. 380,569. (No model.) i

To all whom it may concern:

Be it known that we, VICTOR S. DUPUY and FRANCIS J. FORTIER, ofSyracuse, in the county of Onondaga, in the State of New York, haveinvented new and useful Improvements in Fifth-lVheels, of which thefollowing, taken in connection with the accompanying drawings, is afull, clear, and exact description.

Our invention relates to fifth-wheels for heavy or lumber wagons inwhich a bolster is mounted upon the upper section of the wheel.

Our object is to produce an improved fifthwheel with a bolsterattachment comprising a lower section or bed and an upper sectionconnected together by a circular dovetailing join-t and by a centraldetachable lock, and a bolster-seat detachably secured to the uppersection, the lower section being secured upon the top of the sand-board.

Our invention consists in the several novel features of construction andoperation hereinafter described, and which are specifically set forth inthe claims hereunto annexed.

It is constructed as follows, reference being had to the accompanyingdrawings, in which Figure 1 is an isometrical elevation of our devicecomplete, ready for the bolster to be secured thereto. Fig. 2 is a topplan with the bolster-seat removed. Fig. 3 is a longitudinal verticalsection of the whole device, including the bolster-seat. Fig. 4: is abottom plan of the fifth-wheel. Fig. 5 is an end elevation of the uppersection of the flfthwheel. Fig. 6 is a bottom plan thereof. Fig. 7 1s aside elevation of the bolster-seat detached. Fig. Sis a top plan of thelower section of the fifthwheel.

A is the sand-board, an d 1. 1 are the side bars of the hounds.

B is the lower section of the fifth wheel, secured upon top of thesand-board and provided with curved flanges 2, beveled under, as shown,and with a central circular open ng 3, beveled downward, as shown, andhaving the quadrant-openings 4 cut 1nto the periphery of said circle andopposite each other, and having curved lips 5 upon the edges of thecircle between the quadrant-openings.

C is the upper section of the fifth-wheel, having its ends curved andbeveled so as to properly fit under flanges 2 upon the lower section,having a central circular stud 0 projecting below the lower face of thissection and surrounded by an annular groove 7 of proper size to receivethe lips 5, and having the outwardly-flaring beveled and quadrantshapedflanges a of proper size to pass freely through the openings 4, and theflanges being beveled, to fit the bevel of the opening 3, and having atransverse concavity 8 and a bolthole 9 central to the stud 6, andhaving parallel longitudinal flanges let upon their upper face, eachprovided with a transverse bolt hole.

D is the bolster-seat, provided on its upper and lower face with atransverse convexity 10, the lower part fitting into the concavity 8 andhaving a transverse bolt-hole 11 and having side lips 12, between whichthe bolster lies and to which it is secured. A bolt 13 secures thebolster-seat to the upper section 0.

\Vhat we claim as our invention, and desire to secure by'Letters Patent,is-

l. A fifth-wheel comprising a lower section having curved beveledflanges on its upper face and a central circular aperture, withquadrant-shaped openings on opposite sides thereof and beveled, asshown, and an upper section having beveled ends, a central stud upon itslower face, and beveled quadrantshaped flanges on said stud and adaptedto pass through the lower section, as set forth.

2. A bolster-seat provided with a central transverse enlargement andside ears secured to and in combination with the upper section of afifth-wheel having side flanges, between which the bolster-seat issecured, and with a transverse concavity receiving the convexity belowthe bolster-seat, and the lower section provided with a curved andbeveled seat to receive the curved and beveled ends of the uppersection, as set forth.

3. A fifth-wheel consisting of a lower section provided with curved andbeveled flanges on top, a central circular aperture and quadrant-shapedopenings cut on opposite sides of said aperture and beveled, as shown,and In witness whereof We havehereunto setour having lips on top betweenthe quadrant hands this 3d day of February, 1891.

openings, an upper sectionhavingeurved and VICTOR S. DUPUY. beveledends, and a central stud provided FRANCIS J. FORTIER. withquadrant-shaped projections and having In presence of an annular groovearound the base of the H. P. DENISON,

stud, fitting together, as shown. J. IV. SMITH.
